    Restart analysis with nested do loop causing error

    Zhou, how about writing your loop as a set of commands to a file and then execute that file? So first your loop would create the set of commands that behave like your loop and write them to file and then you would execute that file. *DO,Wvar,1,5,2 !W do loop, Wvar is not used inside of...

    How to create a file .txt with element solution per element with ansys apdl.

    also check *GET command. You should be able to make a loop through all elements and through all their nodes and extract that information

    ANSYS Design

    If you work in ANSYS Workbench then I find SpaceClaim Direct Modeler very good package to deal with CAD. It works with objects rather than tree of operations. It's good for adapting geometry (removing features or errors in imported geometry) that was made elsewhere but I generally use it...

    "ANSYS Workbench" Contact tool reults plotting

    I see. You could try to define path using Construction Geometry feature (right click on Model->Insert). This is used to output results against defined path. But I have doubts whether this will work for contact results. You would need to try. The chances are you will need APDL to do that. Good...

    3 direction spring in ansys workbench

    Hello Miroamiro, If your springs are to be constrained on one side, you could try to use longitudinal spring. When you set the locations of the spring, click one point at your structure and define the second points as slightly off in the direction in which you want the spring acting. Let's say...

    "ANSYS Workbench" Contact tool reults plotting

    Hello Mirghani, can you clarify the first sentence? It's not clear to me what is meant by: with "length" (500mm for example) in the "x-axis" Pavel

    How to calculate stress in beam with varied section?

    Henry, looking at the proportions of the FEA model you showed I suspect the theory doesn't match for few possible reasons: 1, Not a slender beam. Formula σ=(M*y)/I is valid only for fairly slender beams 2, The section variation is too quick along the axis. Meaning that the transmission phase...

    Ansys: how to mesh 3D surface body with Shell elements

    You're welcome Marco! The Workbench Mechanical GUI is quite alright. It just takes some experimenting and trials. You can always export your FEM data via Tools->Write Input File and check what WB does in the background by reading the file in MAPDL. Especially for things like contacts, many...

    ANSYS Workbench - Spreader - Lifting simulation (Stress)

    It is difficult to imagine what is your actual model. I recommend reading something about symmetries generally applicable in structural problems. Symmetry usually helps you to reduce calculation time as well as constrain your model in more comfortable way.

    Ansys: how to mesh 3D surface body with Shell elements

    hi there, I'll just repeat what I wrote for you already on ansysforum.com. Workbench is truly generating shell elements for you. The thickness parameter is necessary for shell elements and cannot be zero, otherwise the stiffness of such body is 0. What you are seeing as 3D elements is the...

    ANSYS Workbench - Spreader - Lifting simulation (Stress)

    Hello Suki, first, symmetrical half is sufficient. It also provides more stability. I would proceed as following: 1, model half of the loadspreader 2, fix the symmetry face all 6 DOF 3, Apply vertical load on the lower lug (10 kN) 4, Apply load in direction of the lifting chain (you know angle...

    How to open Ansys APDL using Excel VBA

    Hi there, I've been making excel sheets with hundreds of runs for parametric models. Here's how I do it: 1, make a batch that executes your analysis (can be written by VBA) 2, run the batch from VBA for point 1: create a batch file (.bat) that runs ANSYS with parameters that will make it: run...
